This register configures operational modes of receive links #0 to #2.
Note
This register is not byte addressable. Writing to this register modifies all the bits
in the register. Byte selection using byte enable signals (CBEB[3:0]) are not
implemented. However, when all four byte enables are negated, no access is
made to this register.
MODE[2:0]:
The mode select bits (MODE[2:0]) configures the corresponding receive link.
Table 16 details this procedure. When link 4m (0?m?7) is configured for
operation in 8.192 Mbps H-MVIP mode (MODE[2:0]=”111”), data cannot be
received on links 4m+1, 4m+2 and 4m+3. However, links 4m+1, 4m+2 and
4m+3 must be configured for 8.192 Mbps H-MVIP mode for correct operation
of the RCAS672. From a channel assignment point of view in the RCAS672
(Registers 0x100, 0x104), time-slots 0 through 31 of the H-MVIP link are
treated as time-slots 0 through 31 of link 4m, time-slots 32 through 63 of the
H-MVIP link are treated as time-slots 0 through 31 of link 4m+1, time-slots 64
through 95 of the H-MVIP link are treated as time-slots 0 through 31 of link
4m+2 and time-slots 96 through 127 of the H-MVIP link are treated as time-
slots 0 through 31 of link 4m+3.
